3M Versaflo TR-371+ Filter Cover with Label Window

Versaflo replacement filter cover with a convenient label viewing window

3M manufacturer's code: 7100156020, model TR-371+.

Keep the filter on your powered air purifying respirator protected with a replacement cover designed for compatible Versaflo equipment. The built-in window lets you view the filter label without removing the cover, making filter identification more convenient. Designed for use with the Versaflo TR-300+ PAPR, this component supports equipment maintenance in manufacturing, metalworking and a wide range of dusty industrial workplaces. It replaces the filter cover, not the filter or the complete respiratory protection system.

Versaflo filter cover features and label visibility

This replacement cover protects a TR-3700 series filter installed on a Versaflo TR-300+ PAPR. It is a protective cover rather than a filtering element. Its key feature is the viewing window, which keeps the filter label visible while the cover remains installed.

Being able to read the label helps with filter identification during equipment checks. Label visibility alone does not establish the condition of the filter media, its remaining service life or its suitability for the contaminants in the workplace.

Filter cover compatibility and system integration

The cover is compatible with Versaflo TR-300, TR-300+ and TR-300N+ series systems. Before replacing the part, check the exact blower, filter and accessory combination against the applicable 3M instructions.

This is a replacement component, not a complete PAPR kit. The blower, filter, battery, breathing tube and headtop or facepiece must form a compatible system configuration. Installing this cover does not change the system’s protection rating.

Industrial applications for the Versaflo filter cover

This cover is relevant wherever a compatible Versaflo PAPR is used in an industrial setting. Applications include manufacturing, metalworking, grinding, sawing, sanding, cutting, foundry work, cement production and powder handling. Pharmaceutical manufacturing is another possible setting, but this replacement part is not limited to cleanroom operations.

For tasks involving silica dust or other airborne particles, the cover is part of the respirator assembly but does not filter the air. Respirator selection must account for the contaminants, exposure concentrations and requirements of the workplace respiratory protection program.

The cover may also be used as part of a welding configuration when the complete system and accessories are suitable for the task. It does not replace a spark protection device. Consult 3M requirements for accessories and protection against hot particles, and confirm the system’s limitations for welding fumes, gases and vapours.

Industrial filter cover inspection, care and replacement

Before use, inspect the cover, viewing window and attachment points. Look for cracks, deformation, contamination or damage that could affect secure installation. Replace damaged components according to the manufacturer’s instructions.

Remove and replace the cover in a safe area away from respiratory hazards. Follow the 3M procedure to remove the cover, check filter installation and fit the replacement part. Confirm that the cover is secure and complete the required respirator checks before returning to work.

Use only cleaning methods and products permitted by 3M. Keep the window clean enough to read the label. A readable label never replaces the need to follow filter change criteria and respond to system warnings.

FAQ about the Versaflo TR-371+ filter cover

What is the purpose of the viewing window?

The window allows you to see the installed filter’s label without removing the cover. It provides convenient access to filter identification without that disassembly step.

Does this cover replace the particulate filter?

No. The cover protects the filter fitted to the blower but does not provide filtration. A compatible filter and a complete respiratory protection system suitable for the exposure are still required.

Which Versaflo respirators can use this cover?

It is compatible with TR-300, TR-300+ and TR-300N+ series systems. Always confirm the exact blower, filter and accessory assembly using the relevant 3M instructions.

Can it be used for silica exposure or welding work?

Yes, as a component of a compatible system suited to the task. The cover alone does not protect against silica, welding fumes or sparks. The exposure assessment and manufacturer requirements determine the necessary system configuration and accessories.

When should the filter cover be replaced?

Replace it if it is cracked, deformed, damaged or no longer attaches securely. Also follow the inspection and replacement criteria provided by 3M.

Complementary suggestions for your Versaflo system

For an industrial worker moving between grinding and material handling in an area with dust or silica exposure, PPE should address the full range of job hazards. Depending on the assessment, gloves (GS13SXPU) can support handling tasks, while eyewear (YASF401BG) and earmuffs (OPH10B) address eye and hearing protection needs. A helmet (TA222) and a vest (VV49) may round out the equipment where head impact hazards and site traffic are present. Check that each PPE item works with the respiratory headtop and the actual working conditions.

When equipping a workstation or developing your Versaflo TR-300 equipment program, consider an industrial kit (RVTR300HIK), then plan charging arrangements with a compatible charger (RVTR342N) and battery (RVTR332). For filtration maintenance, plan for a replacement filter (RVTR3712N5) and prefilter (RVTR3600), after confirming compatibility with your exact configuration and the exposure requirements.
